Linux for migrants: Zorin OS

Some Linux distributions try to find their own way in arrangement of the user desktop. Take, for example, Ubuntu with Unity. Whatever is your opinion about this Desktop Environment, you can’t deny that it brought some fresh ideas as to how to organize the user’s desktop.
At the other pole are Linux distros which intentionally adjust their look to something familiar to users of other operating systems, being it Windows or Mac. Zorin OS is one of those. The intent of such distros is to smooth the transition for users wishing to migrate from Windows to Linux.
Zorin OS exists in several options. Some of them are not free-of-charge, but there are some, namely Core, Lite and Educational, which are free.
This is not my first approach to Zorin OS. I have already written about Zorin OS 4 before. I enjoyed the system, although it lacked stability that time. Did it improve?
